“Leviathan Sellers was built specifically for the post-2025 landscape. Every process — daily auditing, manufacturing cost documentation, manual individual filing, active denial appeals — was designed from scratch around what Amazon now requires.”

I founded Leviathan Sellers in 2025after several years working inside Amazon FBA accounts. I saw firsthand how much money was being silently lost to unclaimed reimbursements, fee overcharges, and IPI issues. When Amazon changed its reimbursement policy in 2025 — cutting the claim window from 18 months to 60 days and switching to manufacturing cost — most existing tools and services simply weren't built to handle it correctly.

Since 2025 I have worked hands-on inside Amazon Seller Central — auditing transactions, preparing manufacturing-cost documentation, filing reimbursement claims, appealing denials, and managing account health for sellers on Amazon US, UK, India, Canada and the EU. Claims are handled personally rather than queued, the documentation is prepared by hand, and recommendations are grounded in real transaction data rather than generic advice.

Our philosophy

We Exist to Recover the Money Amazon Owes You.

Amazon's fulfillment system generates discrepancies at scale. At the volume Amazon operates, a fraction of a percent in errors means real money — your money — sitting in Amazon's account instead of yours.

Our mission: surface the discrepancies hiding in your own reports and turn them into money back. You can work them yourself in Leviathan Recon, or hand the filing to us — either way, claims are documented under the current manufacturing-cost policy, filed before they expire, and appealed rather than written off. No shortcuts, and no automation that puts your account at risk.

Claims are prepared and filed by hand through Amazon's own case system, from the reports you export and upload.

What we stand for

What We Stand For Every Day

Manual Filing, Official Channels

Claims are prepared and filed by hand through Amazon's own case system, with the documentation its current policy requires. We don't use bulk-automation filing or grey-hat tools.

Data-Driven Precision

Decisions based on transaction data, policy documentation, and Amazon's published standards.

Performance Accountability

Reimbursement recovery is performance-based — commission on recovered funds only. We are incentivised to maximise your recovery.

Full Transparency

Monthly statements list the claims filed and what came back on each, including the denials and what we did about them.

Global Expertise

US, UK, India, Canada, EU — localised documentation, currency-aware claims, marketplace-specific knowledge.

Daily Vigilance

The 60-day window means every day matters. We audit daily — never weekly.

Leviathan Recon works from reports you export yourself. There is no API connection to your account and no credential of yours for Recon to hold. You upload the files, and Recon rebuilds your unit ledger from them. The done-for-you work runs on those same uploads. Anything beyond that is agreed with you in writing first.
